Heating accounts for roughly 60 % of your expenditure each and every year on energy bills, so a competent boiler helps make a significant difference.
Modern boilers are a lot more reliable for many different reasons, however primary benefit is that they’re all condensing boilers. All well-managed boilers burn their fuel efficiently, nevertheless they inevitably lose some heat through the hot gases which escape up the flue. A condensing boiler possesses a much larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.
Sometimes the flue gases get so cool that this water vapour around the gas condenses out (hence the name), and a lot more energy is reclaimed through the condensing vapour.
What must i element in when replacing my boiler?
If it is the appropriate time for you to replace your boiler, you will need to decide what type of boiler is ideal for you. Here are a few issues to take into consideration:
If you currently have mains gas, a gas boiler is most likely to represent probably the most inexpensive heating option. Our fuel prices as of March 2016 imply that an oil home heating system happens to be a more affordable choice, however historically oil heating has been more expensive.
In case you don’t have a gas supply in your household, it may come to be worth checking out atype of low carbon heating like a heat pump or biomass. With all the renewable heat incentive this can be a little more inexpensive over-all.
Alternatively you may prefer to secure a gas connection to your household. The business which owns and operates the gas network within your region may be able to help with the cost of acquiring a new connection, and yes it may perhaps even be completely funded. Contact Energy Networks Association for extra information.
Most older gas and oil boilers are normal boilers which could have a standalone very hot water cylinder to store very hot water, as opposed to offering it directly from the boiler. Whenever you replace your boiler you can purchase a brand new regular boiler, and retain your very hot water cylinder, or buy a combi boiler which doesn’t need to have a cylinder.
A standard boiler is more cost-efficient when compared to a combi at producing very hot water in the outset, however some heat is lost from your domestic hot water cylinder, therefore a combi could be better overall.
Your domestic hot water usage
Large households working with many very hot water usually are certainly more pleased with a normal boiler, whereas smaller households using less might be best off with a combi boiler.
Space in your house
Combi boilers do not need warm water cylinders, and thus require less space in the house.
Compatibility with solar water heating
If you’re contemplating installing solar water heating, it’s worth noting a large number of combi boilers are not compatible with this home heating system orcan’t utilize it so efficiently.
